wmnow SCREEN.

Application filed January 31, 1928.

This invention relates to Window screens and has for its object to provide, in a manner as hereinafter set forth, a screen of such class so constructed and arranged. to enable the sliding and tilting thereof when desired, and further whereby the screen can be latched in perpendicular position with respect to a window frame to prevent tilting of the screen when vertically adjusting it. 7

Further objects of the invention are to pro vide, in a manner as hereinafter set forth, a window screen for the purpose referred to which is comparatively simple in its construction and arrangement, strong, durable, compact, thoroughly efiicient inits use, conveniently adjusted, readily installed, with respect to a window frame and comparatively inexpensive to manufacture.

. With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

Referring to the drawings in detail 1 and 2 indicate the sides of a window frame and 3 the bottom rail of the latter. Secured to the inner faces of the sides 1, 2 are guide rails or stiles 4:, 5 respectively and which constis a fragmentary viewin eleva- Serial No. 250,877.

tute tracks for a pair of track swings, to be hereinafter referred to, and which are carried by the screen frame. The guide rails or stiles 4, 5 will be hereinafter termed the track. Projecting from the inner faces of the sides 1, 2 ar'e pins or studs 6 which provide stops for the track swings to be presently'referred to. A window screen, in accordance with this invention, comprises a frame formed of a top rail 7, a bottom rail 8 and a pair of side rails 9, 10. Extending across the opening formed by the screen frame, as well as being secured to the rails 7 to 10 inclusive is a .foraminous panel 11. As shown by way of example the window screen is of rectangular contour. The outer side edges of the rails 9, 10 and the end edges. of the top and bottom rails 8 are rabbeted, as indicated at 12 to oppose the outer sideedges of the track and also one face thereof. See Figure 4. The rabbets of the rails 7, 8 form continuations of the'rabbet in the rails 9, 10. Binding strips 13 are employed for securing the panel 11 to the screen frame and the rails of the latter are rabbeted as at 14 to provide a seat for the marginal portions of the panel 11. See Figure 4:.

Positioned at the ends of the top rail 7 of i the screen frame are track swings 15, 16. The track swings are oppositely disposed with respect to each other and each of which consists of achannel shaped body portion 17, having one side thereof terminating in' a right angularly disposed flange 18 corresponding in length to the length of the body portion 17 and provided with openings 19, 20. The flange 18 is pivotally connected at its upper end to the n'on-rabbeted part of a side of thescreen frame by the pivot 21 which extends through the opening 19. The opening 20 is provided for the passage of a holdfast device to fixedly secure the swings to the screen frame when desired. Normally the swing and screen frame pivot relatively to each other. The body portion 17 straddles a track and also constitutes a guide for the screen when it is movedupwardly and further prevents the upper portion of the screen from disconnecting from the track. The screen can be slid upwardly to the desired point and then shifted on the pivot 21', as illustrated in dotted lines in Figure 2.

Carried at the lower portion of the window screen is a pair of oppositely disposed latch ing members 22, 23 and each of which consists of a lengthwise slotted strap 24: havingian CII inwardly extending angularly disposed stop portion 25 for limiting the outward shift of the latch member. Set screws 26 are provided for detachably securing the latching member in set position. 1 The latching members are adapted to be shifted outwardly with respect to the sides of the frame of the screen for the purpose of opposing the track and when in such position, in connection with the non-rabbeted portion of the screen frame maintains the screen in perpendicular position with respect to the window frame and when the latching members are arranged in such position the screen can be vertically adjusted and slidably coupled to the tracks 4, 5.

Carried by the body portion of each track swing, as well as arranged therein, is aresilient member 27, in the form of an arcuate spring for frictionally coupling-the swing to the track, but the coupling is such as not to interfere with the vertical shifting of the frame, that is to say'the screen frame, when desired. The resilient members 27 also provide means to prevent the shifting of the swings on the track when the screen is tilted.

In Figure 8 a modified form of latching member is shown and which consists of a pivoted strap 28 connected to a side rail 9 or 10 near the lower portion thereof and provided at its inner end with an angularly disposed stop 29 for limiting the pivoting movement in either direction of the strap 28. The pivot for the strap 28 is indicated at 30.

To remove the screen it is necessary to tilt it outward and then tip it up and after such operation the screen can be removed from the tracks.

It isthought the many advantages of a window screen, in accordance with this invention, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which will fall within the scope of the invention as claimed.
